Access Values of Cell Array deeply nested within Structure Array

[babelproofreader]

I have a nested structure_array/cell_array/structure_array of character
values which is the result of a web query which returns a converted JSON
object, the needed numeric value(s) of which I can access in a loop thus:

str2double( S.orderBook.buckets{ loop_ix }.price )

However, I was wondering whether there is a quicker/more elegant way of
getting these values? At the moment, for my purposes, I am having to run a
"look up" for loop that encloses an "if statement" to get in the ballpark of
the required numeric values, and then run a second for loop in the region of
the ballpark to extract these required values.
